Specification of Letters Patent.

Patented May 9, 1916.

Application filed February 15, 1916. Serial No. 78,452.

To all whom it may concern:

Be it known that I, EDWIN G. Bossn, a

\ citizen of the United States, residing at Chicago, Illinois, haveinvented a certain new and useful Improvement in Third- Point Supportsfor Brake-Beams, of which the following is a full, clear, and exactdescription, such as will enableothers skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

Figure 1 is a side elevational view of my improved third point supportfor brake beams. Fig. 2 is a top plan View of the same.

This invention relates to a new and useful improvement in thirdpointsupports for brake beams of the character disclosed in the patentgranted to Charles Haines \Villiams, Jr., No. 997,888, on July 11, 1911.

The object of my present invention is to provide means to prevent thethird point shoe from tilting upwardly over the beam thereby occupyingan abnormal position.

My present invention consists in the provision of a member mounted onthe pivot I pin of the third point supporting shoe,

which member can be used with the types of third point supports now inuse.

In the drawings 1 indicates the strut of a trussed brake beam and 2 thetension member thereof.

3 is the outwardly extending nose shown here as bifurcated between whichbifurcated portions is located the pivoted end of the third pointsupporting shoe 4. 5 is the track with which such shoe cooperates.

6 is the pivot pin on which the shoe is mounted.

7 is a casting pivotally mounted on the 'pivot pin and having crossmembers 8 and 9, which cross members are designed to contact with theparts of the brake beam in the event of any excess movement beingimparted to the shoe and thereby retain said shoe in its normal workingposition. WVhile I have shown cross pleces as being integral with theside pieces, all parts of this pivoted retaining member being integral,it is obvious that the cross pieces could be divided and two independentmovable castings used. In assembling the parts, the casting is slippedover the end of the strut, the chair or shoe then inserted and finallythe pivot pin is introduced into position.

What I claim as new is:

1. A third point support for brake beams comprising a pivoted supportingmember and a pivoted retaining member for preventing'the supportingmember from occupying an abnormal position.

2. A third point support for brake beams comprising a pivoted supportingmember, and a pivoted retaining member having means for contacting withthe supporting member and a part of the brake beam, whereby thesupporting member is prevented from occupying an abnormal position.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses, this tenth day of February, 1916.

EDWIN G. BUSSE.
